I am sure there are a lot of people who have this problem, but I cannot get my validation emails through to many email inboxes. I had my website on shared hosting and 100% of the validation emails got through.

Then last week I moved the website to my own server, I did not change anything, just moved the site over as is.

Now comcast, verizon, att, bellsouth, hotmail and a few others block my validation emails. I double checked and I am running the correct PTR(reserve dns zone) record.

Does anyone really know how to fix this problem? Is it even possible?
